Bodyline Products International 216FD User Manual

As there are many factors that affect bandwidth, it is very difficult to predict the required 

amounts. The settings that affect bandwidth are:

• image resolution
• image compression
• frame  rate
• MPEG-4 GOV settings
• bit rate control settings

There are also factors in the monitored scene that will affect the bandwidth. These are: 

• amount of motion
• image complexity
• lighting conditions

For MPEG-4, if there is only limited bandwidth available, and if this is more important 

than the image quality, using a constant bit rate (CBR) is recommended. Use a variable bit 

rate (VBR) if the image quality needs to be maintained at a higher level. If supported on the 

network, consider also using MPEG-4 multicasting, as the bandwidth consumption will be 

much lower.
